Copper Alloy C96700-M01 vs C96700-TF00
Copper Alloy · C96700 temper comparison
C96700-M01 and C96700-TF00 are two conditions of the same copper alloy grade, C96700: M01 (as sand cast) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C96700-TF00 is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 275 MPa (39.9 ksi) for C96700-M01, about 125% more; tensile strength follows at 760 MPa (110 ksi) vs 450 MPa (65.3 ksi). In exchange, C96700-M01 is the more ductile: elongation 10% versus 5% for C96700-TF00, and C96700-TF00 is harder (330 HB vs 150 HB). C96700-TF00 runs hotter in service (315°C vs 200°C continuous) and C96700-TF00 conducts heat better (33 W/m·K vs 29 W/m·K).
C96700-M01Choose it when the part is bent, formed or impact-loaded.
C96700-TF00Choose it when strength drives the design, or when the part sees heat.
C96700-M01 vs C96700-TF00: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

C96700-M01 vs C96700-TF00 — frequently asked
Is C96700-TF00 stronger than C96700-M01?
Yes. C96700-TF00 has a typical yield strength of 620 MPa (89.9 ksi) against 275 MPa (39.9 ksi) for C96700-M01 — about 125% more. Tensile strength is 760 MPa (110 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, M01 or TF00?
TF00 is the default C96700 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, C96700-M01 or C96700-TF00?
C96700-M01, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for C96700-TF00; for welding the order is C96700-M01 first (fair, 40/100) then C96700-TF00 (fair, 35/100).
